Functional Diagram
• High dynamic range downconverter
The CV210-1A is a dual-channel high-linearity down-
converter designed to meet the demanding performance,
functionality, and cost goals of current and next generation
mobile infrastructure basestations. It provides high
dynamic range performance in a low profile surface-mount
leadless package that measures 6x6 mm square.

It is ideally suited for high dynamic range receiver front
ends using diversity receive channels. Functionality
includes frequency conversion and IF amplification,
while an integrated LO driver amplifier powers the
passive mixer. The MCM is implemented with reliable
and mature GAs MESFET and InGaP HBT technology.

1. Specifications when using the application specific circuit (shown on page 3) with a low side LO = 0 dBm and IF = 75 MHz in a downconverting application at 25° C.
2. IF matching components affect the center IF frequency. Proper component values for other IF center frequencies than shown can be provided by emailing to applications.engineering@wj.com.
3. The IF bandwidth of the converter is defined as 15% around any center frequency in its operating IF frequency range. The bandwidth is determined with external components. Specifications are valid around
the total ±7.5% bandwidth. ie. with a center frequency of 80 MHz, the specifications are valid from 80 ± 6 MHz.
4. Assumes the supply voltage = +5 V. IIP3 is measured with Δf = 1 MHz with RFin = -5 dBm / tone.
5. Assumes LO injection noise is filtered at the thermal noise floor, -174 dBm/Hz, at the RF, IF, and Image frequencies.
6. The maximum junction temperature ensures a minimum MTBF rating of 1 million hours of usage.
